ulTIMiFlux
line of thermal interface materials offer high performance, low cost,
configurability and custom sizes for your thermal system needs. Thermal Interface Materials (TIM) are
a secondary material installed between the heat sink and the device which are designed to improve the
thermal transfer to the heat sink. Regardless of how flat or smooth the device and heat sink are, there
will always be small air voids between the two surfaces. Since air is a not a great conductor of heat, a
TIM replaces the air and fills the voids. There are many types of TIMs and each has its best case
usages. Wakefield-Vetts’s line of dielectric phase change thermal materials are intended to fill voids
between a device and the heat sink and utilizes a polyimide film to act as a thermally conductive carrier
in order to deliver a uniform thickness coating of phase-change thermal compound on both sides.
Through the development of this unique formulation,
Wakefield-Vette’s phase change solution offers
efficient thermal transfer by phase-changing during
normal device operating temperatures while
maintaining a uniform bond line thus driving out the
air and adjusting for any surface imperfections or
flatness conditions that may exist across the interface.
This construction is useful in a wide range of
electronic cooling applications from transistors,
diodes or any type of heat generating non-isolated
power device.

Phase Change Compound
A primary advantage of utilizing a phase-
change system is the ability to drive out air
from within the interface during initial device
cycling causing phase change and surface
wetting of the thermal compound coating.
The phase-change compound is available in
specific die cut patterns for common TO
packages and can be placed instantly and
immediately ready for component mounting.
Due to it’s thixotropic formulation design,
compound is held within the interface with no
worries of run-out into unwanted areas during
normal device/component operation.

Wakefield-Vette's phase-change product is a solvent free high performance dielectric thermal interface material
that is designed to provide efficient thermal transfer by providing precision phase-change and a uniform bond line
thickness across a device/component mounting interface. The pads are designed as a pre-formed thermally
conductive “drop in place” solution that offers excellent thermal transfer characteristics. From an installation
perspective, thermal greases are difficult to dispense as well as provide inadequate coverage and a uniform
thickness across the interface most often leaving trapped air leading to poor thermal transfer. Not to mention the
thermal grease clean up required in unwanted areas afterwards.
Wakefield-Vette offers the following pad sizes and die-cut TO package sizes for ease of installation:
